I am focusing on shapes being simultaneously solid and porous, planes tipping forward and back, and angles intersecting curves.
Paint is a marvelous material for me. My way of applying paint is to do so in many layers. I sort of scrub the paint on in many applications. The result of this build-up method is that the paint responds to light. Paintings appear differently at different times of day. In one light a painting can seem yellow or gold and at another time of day, it will look as if it is pale white. I love that paintings change depending on the light.
